jiixer Posted July 31, 2005 Share Posted July 31, 2005 Ok random thing, One day I start the beast and the ABS light stays on.... oops I think, ah well, well go anyway, Turn the Slip cont off as I always do. ! mile ish after warm up the Slip light starts to flash!!! Test ABS and nope, its not there. Symptoms. ABS Light on - NO ABS Slip Cont light flashes after small drive ECU - NO ERROR CODES!! Checked ABS ECU (ie the connections) Checked Fuse (Cant find relay) Im stumped!!!! Jiixer Quote Link to comment Share on other sites More sharing options...
Nic Posted July 31, 2005 Share Posted July 31, 2005 If there is a problem with one of the ABS sensors/or signal from it, you will get both lights come on. If the ECU realises one ABS sensor is not working it completely disables the ABS. The stock trction control uses the ABS sensors also. They also both use a separate ECU above the stereo which could be another cause of the problem, have you had the dash off recently? Quote Link to comment Share on other sites More sharing options...
jiixer Posted July 31, 2005 Author Share Posted July 31, 2005 Yes the dash has been out repeatedly, but im very careful to put back everything carefullt=y, and I have ched it all!!! OK so what are these ecue's? > Cream color, two plugs (i think) 1st above Stereo Brown one samller sits above that ecu, one plug > 2 Silver ecu's sat on top of eachother. Any help appreciated!!!

Jezz Posted July 31, 2005 Share Posted July 31, 2005 Ok, brown plastic ecu above stereo is electric ariel relay, white ish plastic one is an abs ecu, two lower ones have metal casings, lower is trac cont and abs, and top one (this one i,m not sure of) is also abs. I,m also having flashing 'slip cont off' problems! Tried everything so b***ocks to it, getting RLTC fitted next week!!! Quote Link to comment Share on other sites More sharing options...
jiixer Posted July 31, 2005 Author Share Posted July 31, 2005 I dont like traction control anyway, but I do like ABS!!! anyone know any way of testing these? Quote Link to comment Share on other sites More sharing options...
jiixer Posted July 31, 2005 Author Share Posted July 31, 2005 PS*** So wich one is the Active spoiler ecu then? Quote Link to comment Share on other sites More sharing options...
Ian C Posted July 31, 2005 Share Posted July 31, 2005 Ahahaha - did you know you can check the ABS ecu for stored fault codes, much like the engine ECU? 1. Turn your ignition *on* 2. In the diagnostics port, unplug the short connector from the bottom right (it's a bit of metal that joins two pins) 3. Use a jumper wire on pins TC and E1 4. Your ABS warning light will now behave like the check engine light, as in: "If system is functioning properly, ABS light will flash 2 times per second. If a malfunction is detected, 4 seconds will elapse, then ABS light will begin flashing 2-digit DTC. ABS light will flash first digit of DTC, followed by a 1.5-second pause, then second digit of DTC. If 2 or more DTCs are stored, a 2.5-second pause will separate DTCs. After all DTCs are flashed, there will be a 4-second pause, then all DTCs will repeat." ('DTC' being the error code) See if you have any stored codes - post 'em up if you do and I'll look up the errors. Wait until you find out the funky way of clearing the stored codes, it's right cool -Ian Quote Link to comment Share on other sites More sharing options...

jiixer Posted August 1, 2005 Author Share Posted August 1, 2005 Ok strange.... Clipped the Ports and checked the light.... firstly I noticed the Cruise Control light was flashing continuiously, and then the ABS light..... did this.... Ignition on >> Lit for 1 second >> Unlit for 1 second >> Then on constantly...... forever!! Tested this 5 times.. same results.... Shed any light?

Ian C Posted August 1, 2005 Share Posted August 1, 2005 You did put the ignition on before the rest of the steps...? I don't know if it'd make a difference but the instructions are pretty clear that the ignition should be on when you take out the short pin and put in the bridge wire... -Ian Quote Link to comment Share on other sites More sharing options...

madmunky Posted November 21, 2007 Share Posted November 21, 2007 Thanks for the ABS guide can anyone help me out with my error codes as its MOT time early next year so trying to sort out all the little problems, I think I have three codes 32 33 35 Anyone able to tell me what they mean Quote Link to comment Share on other sites More sharing options...

Ian C Posted November 22, 2007 Share Posted November 22, 2007 Code 32 Malfunction of left front wheel speed sensor signal. Check speed sensor, sensor rotor, wiring harness, and connector. Code 33 Malfunction of speed sensor signal for right rear wheel. Check speed sensor, sensor rotor, wiring harness, and connector. Code 35 Open in left front wheel or right rear speed sensor circuit. Check speed sensor, sensor rotor, wiring harness, and connector. Sounds like you've got a wiring issue that is taking out the left front and right rear wheel sensor signals. There isn't much chance of two opposite corners having their sensor fail at the same time so there must be a common cause, I'll have a look at the circuit diagrams... -Ian Quote Link to comment Share on other sites More sharing options...
madmunky Posted November 22, 2007 Share Posted November 22, 2007 Thanks Ian do you have the circuit diagram for the ABS? Quote Link to comment Share on other sites More sharing options...
Ian C Posted November 22, 2007 Share Posted November 22, 2007 Hum, there is no common wiring. I noticed it says "or" and not "and" under code 25 though. Have you cleared the codes and then gone for a test drive to see if it logs the same codes or just maybe one of them? Also have you got anything like RLTC wired into the ABS system? -Ian Quote Link to comment Share on other sites More sharing options...
Ian C Posted November 22, 2007 Share Posted November 22, 2007 Thanks Ian do you have the circuit diagram for the ABS? There are multiple pages of the stuff alas I got most of my reference material off mkiv.com Quote Link to comment Share on other sites More sharing options...
madmunky Posted November 22, 2007 Share Posted November 22, 2007 Ok thanks, there is no RLTC yet do you clear the ABS codes the same and ECU code i.e. disconnect the battery? Quote Link to comment Share on other sites More sharing options...
Ian C Posted November 22, 2007 Share Posted November 22, 2007 Disconnecting the battery is the sledgehammer method There is a much cooler way of clearing the ABS fault codes - while it is flashing the fault codes at you, tap the brake pedal 8 times withing 3 seconds and you'll see the flashing light go back to a steady "clear" signal. -Ian Quote Link to comment Share on other sites More sharing options...

mustang Posted February 19, 2010 Share Posted February 19, 2010 Jim, Ian posted the ABS error codes in my thread - http://www.mkivsupra.net/vbb/showthread.php?t=210087 It seems we're having similar problems. Afik the ignition should be at position 2 engine not running. Quote Link to comment Share on other sites More sharing options...
